These CDs have a Serato exclusive and unique control signal which allows Scratch Live to track the motion of the CD in the player, simulating the same movement with digital audio. Since CDs can be lost or scratched, it is smart to have a couple spares with you before any show. These factory-made CDs are more durable than CD-Rs you can burn yourself.

Two tracks: 1. Play 15 minutes 2. Select.
